In this study, 60 Ukrainian and 53 Hungarian carp, aged +1 to +5 years, with body lengths ranging from 8 to 76cm and total weights between 11 and 8800 grams, were used at the experimental base of the Fisheries Research Institute. In addition, in April 2020, 500 samples of Hungarian carp fry and +1 to +3-year-old fish were obtained from the Al-Said farm in the Ishtikhon District, Samarkand Region. The determination of morpho-biochemical blood indicators was considered one of the main criteria in evaluating the fish grown in the research. Regarding the reproductive characteristics of Hungarian carp, the average absolute fertility of females was 886,700-254,700 eggs more than that of the Ukrainian carp. An increase in caviar spawning ensured a 12.8% rise in larval output (productivity). One of the most effective methods for developing high-yield breeds is fish hybridization. Typically, first-generation hybrids demonstrated high fishery value. It was found that the fertility level of carp females of different origins (Ukrainian and Hungarian) varied greatly. This variability made it possible to select and form broodstock characterized by high productivity and to obtain hybrid offspring from highly fertile females.
